(a) find value of x

(b) if the number of taxis was 66 calculate the total number of vehicles included in the survey.​

Answer 1

Step-by-step explanation:

(a)the sum of all angles in a pie chart is 360°

5x+2x+52=360

7x=308

x=44

(b) the no.of =66

2x°=66

1° = 66/88

1° =3/4

the no. of buses= 52×3/4

= 39

the no. of others. = 5(44)×3/4

=55×3

=165

the total no. of vehicles = 39+165+66

= 270

Answer 2

Answer:

a. 44

b. 270

Step-by-step explanation:

a) total = 2x° + 5x° +52° = 360°

7x° = 308

x° = 44

b). 2x° = 66

2*44° = 66

360° = 270
